Abstract
A first network device includes: a transceiver, configured to send control information to a terminal, to instruct the terminal to access a second network device and query whether the second network device allows the first network device to use a first spectrum; and a processor, configured to: determine a query result of the terminal, and determine, according to the query result, whether the first spectrum is available, where the first spectrum is an unlicensed spectrum for the first network device.

A method for determining availability of a communication spectrum, comprising:
- receiving, by a terminal, control information sent by a first network device;
- according to the control information, accessing, by the terminal, a second network device and querying whether the second network device allows the first network device to use a first spectrum;
- receiving, by the terminal, feedback information returned by the second network device in response to the query;
- determining, by the terminal according to the feedback information, whether the first network device is allowed to use the first spectrum;
- and/or
- determining, by the terminal, query result information of the query according to the feedback information, and sending the determined query result information to the first network device;
- wherein the first spectrum is an unlicensed spectrum for the first network device.
A method for determining availability of a communication spectrum, comprising:
- detecting, by a second network device, that a terminal accesses the second network device and queries whether the second network device allows the first network device to use a first spectrum;
- determining, by the second network device, whether to allow the first network device to use the first spectrum;
- and
- sending, by the second network device, feedback information to the terminal in response to the query, wherein the feedback information is used for indicating whether the second network device allows the first network device to use the first spectrum;
- wherein the first spectrum is an unlicensed spectrum for the first network device.
A method for performing communication on an unlicensed spectrum, comprising:
- receiving, by a terminal, control information sent by a first network device, wherein the control information is used for instructing the terminal to access a second network device and instruct the second network device to stop using a first spectrum;
- according to the control information, accessing, by the terminal, the second network device and instructing the second network device to stop using the first spectrum;
- wherein the first spectrum is an unlicensed spectrum for the first network device;
- wherein the control information comprises configuration information and activation information, the configuration information comprises information about a physical resource and/or a physical signal used when the terminal accesses the second network device, and the activation information is used for instructing the terminal to access the second network device according to the configuration information;
- and
- receiving the control information, and accessing the second network device according to the control information comprises:
- receiving and storing, by the terminal, the configuration information, and accessing the second network device according to the configuration information after receiving the activation information;
- or
- the control information comprises the configuration information, and receiving the control information, and accesses the second network device according to the control information comprises:
- receiving, by the terminal, the configuration information, and accessing the second network device according to the configuration information.
